I'd like to report an issue experienced with the latest Oneiric, Dell N5110, and IDT STAC92HD87 which has been explored through quite a few steps already, and seems to have bottomed out to a set of pins/controls/flags which are not being properly managed in order to toggle speaker activation when a headphone is inserted.
So far, I haven't heard sound from my speakers at all, although within Alsamixer, the Speaker volume is visibly toggled from 100% to MM (mute) on headphone insertion.
I've tried every model against snd-hda-intel, many different other options, and started to explore the HDA Analyzer, which includes controls named like this...
Node 0x13 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out R/L Device: name="STAC92xx Analog", type="Audio", device=0 Control: name="Speaker Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=1, idx=0, ofs=63 Control: name="Speaker Playback Switch", index=0, device=0 ControlAmp: chs=3, dir=1, idx=0, ofs=0 Amp-Out caps: ofs=0x7f, nsteps=0x7f, stepsize=0x02, mute=1 Amp-Out vals: [0x7f 0x7f] Converter: stream=5, channel=0 Power: setting=D0, actual=D0 Delay: 13 samples
...but toggling these checkboxes within the HDA Analyzer gui doesn't trigger any sound from the speakers either. It could be a rich combination of the very many checkboxes and sliders which are revealed by the Analyzer, but I don't really know where to start. The bug information downstream is here...

I'd really welcome suggestions for what else to try and happy to invest time exploring options to try and make ALSA better still.
